If A + A = B
And A - B = C
Then what is C?

A+A=B
2A=B
A-2A = C
-A = C

👆 this is good, destroyer, but it's a mathematical impossibility. You can't just "cancel" AB-AB from both sides, because AB-AB is always zero.

Sorry, you can't divide by zero in THIS example because a=b in THIS example, and so AB - AB is the same as saying 2A - 2A.
Dude fuck math I can't believe I'm arguing this. 😖

It is quiet simple, If no brackets nor parenthesis are present, seperate it at the "+" and "-" sign, solve in between then add/subtract and there's your answer c). 41

I guess what I read about Americans being terrible at math is true; the people on Facebook keep saying one. One of them even told me to go back to school lmao.

Solve for x
26= 12x-x^2(x squared) -1

Most Americans are. We still have hope though.

I choose not to answer that😊

Yup.
0=-(x^2-12x+27)
0=-(x-9)(x-3)
X=9V3

What about 0=(x^2)+4?

All you anal retentive teacher's pet arithmetic (it's not "math") nerds are missing the point.

What exactly is precedence? Why is it?

It's arbitrary. It's a set of implied rules designed to remove ambiguity from ambiguous statements.

Precedence is spelled out for calculators and programming languages precisely because it is not fixed, nor universal.

If you have a special agreement between you and your "math" teacher, that's great. But don't expect it to be binding for the rest of the world.

Learn to communicate without so much ambiguity and we wouldn't have this problem.

If you have one liter of salt, and consume 12 servings, how much salt do you have left?

A) I can't answer this because the definition of "serving" is unknown.

B) I can't answer this because I do not know the temperature, altitude, or packed density of the salt. "Servings" are usually by weight, not by volume.

C) 910 grams

D) 932 ml

If you don't answer D, you are a moron. Go back to school.

this is in the sane vein as:

A)0
B)13
C)14

B is right, because of the priority rule:
() first
/x second
And - + last
